Signals in Angular allow developers to create dynamic and responsive UIs by managing state changes. This involves three reactive primitives: writable signals (modifiable directly), computed signals (values derived and automatically updated from other signals), and effects (functions triggered by signal changes). Signals improve performance by enabling fine-grained reactivity, updating only affected program areas. The post also discusses signal usage in frameworks like Solid.js, React, Vue.js, and Svelte, and highlights a proposed JavaScript standard for signals aimed at unifying this approach across frameworks.
